BEARING MEMBER FOR IRON noons.

Specification of Letters Patent.

To all whom it may concern: I I

Be it known that I, BENJAMIN VVnxLnn,

a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new useful Improvements in Bearing Members for Iron Doors, of which the following is a specification.

. This invention relates to improvements in bearing members for iron doors, and particularly. to bearing members formed of parts of the iron door frames at the side edges. I

e The object of my invention is to provide suchbearing members formed out of part of the frame of the door and projecting beyond said frame, which bearing members .are held against movement toward the door proper and against movement transversely to their length, thereby preventing accipdental wdisplacement transversely to the length of the bearing members, and also preventing the bearing members from being "pushed back toward the edge of the door,

but at the sametime permitting such bearing members to yield to the effects of heat, when the door is subjected to fire orgreat heat, or the parts of the same become heated, all of which is very simple in construction, strong, durable and reliable and effective in action. I 1 l i In the'acco'mpanying drawings in which like letters of reference indicate like parts Figure 1 'is a face view of a door, parts being brokenaway, provided with my new and improved bearing" member and a bar against which the bearing member can rest,

40 and which barforms a guide on which the bearing member can run up and down while guiding the door in its vertical movements. Fig. 2 1s an enlarged view ofthe bearing members. c

angle bars or T-irons, the T-iron construc-- 'tion being preferred and to the said T-iron frame a corrugated iron filling 4 or other panels are suitably attached. An angle iron 5 attached, along one or its flanges, to the" and - inch, more or Fig. 3 is a horizontal sectional view on the i bearin iron frame of the door section, so that the other flange projects lengthwise of the door, beyond the edge of the frame. A door mounted in thismanner, in order not to run too loosely, would have have the free edge of the flange 6 of the angle iron 5 close to the vertical guide bar 2. That,how-

ever, is objectionable, for in case of fire when the door expands, the angle iron 5 would be ammed against the. guide 2 and the door would buckle and the parts would become locked, and such a construction is not permrss lble. ofsuch dimensions that the free edge of the For that reason the door ismade flange 6 of the angle iron 5 is some distance from the vertical guide bar 2, say from onehalf to three-quarters of an inch. A

The bearing piece 7 is formed byfcutting a slot 8 in the flange 6 of the angle "iron 5,

and bending the material between the slot and one edge. of the flange outward "at one end, at which end the slot extends to the edge of the flange, thematerial bent outward constituting the bearing, piece, which bearingpiece is thus united withthe flange 6 at its lower end, and at its upper end is entirely detached fromthe flange. The cut projects about one-half an inch, more or.

less, beyond the free edge of the flange 6 and is close to the guide rail 2, as the door moves up and downward.

1 As the bearing pieces 7 on the opposite ends of the door are close to their respective guide rails 2 and project beyond the free edges of the flanges 6 for about a half an less, the outer edges of the flanges 6 are so far away from the guide rails 2, that said flanges6 can move laterally under the eflect of heat about a half an inch, more or less, before they will contact with the guide rails.

If the doors expand under the effect of heat, the pressure produced by said expansion,'forces the bearing pieces 7 into the recesses formed by making'slots 8 andbend ing outward the pieces 7.. I thus have a g iece which guides the door propeirly without danger of blndi'rig 1n case of The bearing piece 7, which is free at its upper end, is very apt to be bent laterally during transportation of the door, or while erecting the same, or even while in use, and to prevent such bending, I secure washer plates 9 to the opposite surfaces of the bearing piece 7, at the free end of the same, which washer plates extend to or beyond the outer edges of the upper end of the bearing piece 7 and laps over the solid part of the flange 6, as shown at 12, thus preventing any lateral movement of the bearing piece 7. c

' The bearing piece is also apt to be bent inward and toward the end edge of the door and thereby cause looseness in the door, through frequent manipulation of the door, or carelessness in mounting and is also apt to be forced, by successive hammering and wear and tear, backinto the recess from whichit was originally bent. To prevent this I provide the washer resting against the inner surface of the flange 6, with divergingcurved arms 11 which bear against that flange of the angle iron 5 which is attached directly to the frame of the door and at the same time they rest on the adjacent surface of the flange 6. These arms have convexinner edges, facing the base of the angle iron 5, and" their outer edges are concave, so that the arms. are thinnest where they emerge from the washer di'sk'9. These arms are of sufficient strength to hold the bearing piece 7 projected beyond the edge of theflange 6 during ordinary usage and to prevent inward displacement of such bearing piece during transportation and while erecting the doors.

When, in case of fire, the doors become heated and expand, the arms 11 also become heated, more or less, and can easily bend at their thinnest point, which is at their juncture with the washer disk 9 and can diverge still more under the pressure produced by the heat, between'the bearing piece and the guide bar 2, thus permitting the bearing piece 7 to be forced into its recess.

So as to prevent the parts from catching on the arms 11, they are beveled at their" concave edges toward the flange 6, as shown at 14:.

Normally the upper end of the bearing piece extends outward beyond the end of the "When the door becomes heated and the bearing-piece 7 is subjected to the pressure produced by such heat, the bearing piece can lo e forced into its recess 8 and the arms 11 can bend under pressure on the bearlng piece. As the door expands, the edge of the flange 6 of the angle iron moves towardthe guide 2 and in. the same proportion, the

bearing piece .7 is forced back into'the recess 8, so at no time, whether the door is cold or hot, is there any danger of the door binding or buckling.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

l. The combination with a vertically slid ing door and a guide therefor of bearing members projecting beyond the extreme side plate on the side edge of the door, part of said plate being bent outward to form a bearing member which at 1ts outer end proj ects beyond the edge of-the plate, and washers on the free end of said bearing member, o erlapping part of the web from which the bearing member is cut, substantially asset forth.

3. The combination with a vertically movable door and a guide rail for the same, of a plate on the side edge of the door, part of said plate being bent outward to .form a bearing member which at its outer end proj ects beyond the edge of the plate, and washers on the free end of said bearing member,

overlapping part of the web from which the caring member is'cut and wings projecting from one of said washer plates to aplate on the door, substantially as set forth.

4E. The combination with a vertically movable door and a guide rail for the same, of a plate on the side edge of the door, part of said plate being bent outward to form a bearing member which at its outerend projects beyond the edge of the plate, and washers on the free end of said bearing member, overlapping part of the web from which the bearing member is cut, diverging wings extending from said washer plate'to a bearing plate on the door, which wings have convex inner edges and concave outer edges, substantially as set forth.

5. The combination with a vertically movable door and a guide rail for the same, of a plate on the side edgeof the door, part of said plate being bent outward to. form a bearing member which at its outer end projects beyond the edge of the plate, and washers onthe free'end of said bearing member,

overlapping part of the web from which the bearing member is cut, diverging wings extending from said washer plate to a bearing plate on the door, which wings have convex inner edges and concave outer edges, the wings being beveled at the convex edges, substantially as set forth.

6. The combination with a vertically movable door and a guide rail for the same, of a plate on the side edge of the door, part of said plate being bent outward to form a bearing member which at its outer end projects beyond the edge of the plate, and washers on the free end of said bearing member, overlapping part of the web from which the bearing member is cut, diverging wings extending from said washer plate to a bear ing plate on the door, which wings have convex inner edges and concave outer edges, said wings containing less metal in cross section, adjacent to the washer plates, than in the remaining part of the length, substantially as set forth.
